BACKGROUND 1. Field

This disclosed subject matter relates generally to methods, systems, andproducts for matching unrelated data sets and, in some particularembodiments or aspects, to a method, system, and computer programproduct for matching unrelated card transaction data to mobileapplication data.

2. Technical Considerations

With the growth of the usage of smart phones and other technologies,there has been a large increase in anonymized data available aboutusers, including purchasing information, transaction information, mobilephone application information, banking information, locationinformation, and/or the like. This information can be used to betterunderstand users in order to determine their preferences and to allowfor more targeted advertisements to gain new customers or grow existingcustomers. However, various types of data are often found in separatedatabases such that there may not be a key to easily join data from onegroup with the data of another group. For example, there is no commonidentifier between mobile phone application information and transactioninformation. Therefore, it is necessary to be able to match the datafrom one database to the data of another database to identify the sameuser's information between both databases.

It has been difficult to identify a mobile phone user based on themobile application data of their user device, such as what mobileapplications they use, when they use it, and where they use it. Thepresent disclosure provides a system, method, and computer programproduct that allows for an entity to match an identity from an accountidentifier to an identity from a mobile user identifier based ontransaction data and mobile application data by comparing the locationsof account transactions to the locations of interactions with one ormore mobile applications. The current disclosure allows for an entity togain additional information about a user from other sources that keepthe identities of their users anonymous. This allows the entity toprovide better service to a customer or client by identifying customerpreferences by identifying activities and interests of the customer fromoutside sources. The systems and methods disclosed herein also allow fordecreased computational resource usage. A finer mesh of regions resultsin increased computational resources to generate the regions andidentify which regions used in the disclosed methodology are associatedwith each transaction and interaction. By starting with a less finemesh, and creating finer meshes as needed, less computational resourcesare utilized when generating the mesh of regions. Additionally, too fineof a mesh may result in less confident matches as a user will often movelocations between making a transaction and making an interaction.Therefore, an interaction and a transaction are less likely to belocated in the same region if the regions are too small. Non-limitingembodiments described herein allow for increased accuracy and confidencewhen matching a user to an account by either altering the geographicregion size or by altering a timing threshold difference between thetransaction time and the time of the interaction.

The number and arrangement of components shown in FIG. 2 are provided asan example. In some non-limiting embodiments or aspects, device 200 mayinclude additional components, fewer components, different components,or differently arranged components than those shown in FIG. 2 .Additionally or alternatively, a set of components (e.g., one or morecomponents) of device 200 may perform one or more functions described asbeing performed by another set of components of device 200.

Referring now to FIG. 3 , FIG. 3 is a flowchart of a non-limitingembodiment or aspect of a process 300 for matching transaction data withmobile application data. In some non-limiting embodiments or aspects,one or more of the steps of process 300 may be performed (e.g.,completely, partially, and/or the like) by a transaction processingsystem. In some non-limiting embodiments or aspects, one or more of thesteps of process 300 may be performed (e.g., completely, partially,and/or the like) by another system, another device, another group ofsystems, or another group of devices, separate from or includingmerchant systems, acquirer systems, and/or issuer systems.

As shown in FIG. 3 , at step 302, process 300 may include generating aplurality of regions within a geographic area. The regions and/orgeographic area may defined by geographic coordinates, streets, cityblocks, zip codes, cities, states, provinces, countries, addresses,radius and/or distance from an address and/or geographic coordinate,artificial boundaries, and/or the like. In some non-limiting embodimentsor aspects, the size of the regions may be predetermined and may bebased on computational time to generate the regions. In somenon-limiting embodiments, the size of the regions may be determined by amachine learning algorithm. For example, the machine learning algorithmmay determine the sizes of regions based on the sizes of previousregions that resulted in linking user identifiers to account identifiers(e.g., linking a single user identifier to a single account identifier)based on previously analyzed transaction data and mobile applicationdata. Each region may be associated with a unique region identifier. Theregion identifier may be a numerical value, alphabetical value, and/oran alphanumerical value.

In some non-limiting embodiments or aspects, the number of regionswithin the geographic area may be predetermined. In some non-limitingembodiments or aspects, the size of the regions may be determined basedon land area, population, number of merchants, and/or the like. In somenon-limiting embodiments or aspects, the regions may be defined by apolygon defined by a convex hull algorithm. The regions may be definedsuch that the regions do not overlap with each other. A region may shareat least a portion of its boundary line with another region.

In some non-limiting embodiments or aspects, each neighborhood may beassociated with a unique neighborhood identifier. A neighborhood mayinclude the geographic area(s) enclosed by a specified region (e.g., acenter region) and all regions adjacent to the specified region.Adjacent regions may include regions which share at least a portion ofthe boundary line of the specified region. A neighborhood may be definedfor more than one region, or may be defined for every region, whereineach region is the specified region for its own associated neighborhood.More than one neighborhood may overlap with another neighborhood. Aregion may be included in more than one neighborhood such that it is thespecified region in one neighborhood and may be an adjacent region inone or more neighborhoods.

FIG. 5 shows an example of neighborhoods according to some non-limitingembodiments or aspects. In this example, the first neighborhood 520 isassociated with center region 501, and the second neighborhood 530 isassociated with center region 502. The first neighborhood's centerregion 501 is adjacent to regions 502, 503, 504, and 505. Therefore, thefirst neighborhood 520 may be determined to be associated with thegeographic areas enclosed by regions 501, 502, 503, 504, and 505. Thesecond neighborhood's center region 502 is adjacent to neighborhoods501, 504, 505, 506, and 507. Therefore, the second neighborhood 530 maybe determined to be associated with the geographic areas enclosed byregions 501, 502, 504, 505, 506, and 507. In this example, regions 501,502, 504, and 505 are included in both the first neighborhood 520 andthe second neighborhood 530. In this example, regions 508, 509, and 510are not adjacent to either 501 or 502, and thus are not included in thefirst neighborhood 520 or the second neighborhood 530.

Referring back to FIG. 3 , at step 304, the process 300 may includereceiving transaction data associated with a plurality of transactionsconducted between a plurality of accounts and a plurality of merchantsusing a plurality of account identifiers. The transaction data mayinclude, for example, an account identifier and a transaction locationfor each transaction. The transaction location may include the merchantname and/or identifier, merchant category, and/or a geographic location,such as an address, a zip code, geographic coordinates, and/or the like.The transaction data may also include the date and/or time oftransaction.

In some non-limiting embodiments or aspects, the transaction datareceived may be from a predetermined period of time. For example, thetransaction data may be for transactions initiated on a particular day,or from a range of dates and/or times. The transaction data may be fortransactions initiated within a particular range of hours, for example.

With continued reference to FIG. 3 , at step 306, process 300 mayinclude receiving mobile application data associated with at least oneinteraction between at least one mobile device user and at least onemobile application using a plurality of user identifiers (e.g.,interaction data). The mobile application data may include a useridentifier, connection type (e.g., WiFi®, mobile data, and/or the like),type of mobile device, and an interaction location for each interaction.The interaction location may include the mobile application name and/oridentifier, and/or a geographic location, such as an address, a zipcode, geographic coordinates (e.g. latitudinal/longitudinal coordinatesand/or the like), and/or the like. The mobile application data mayinclude the date and/or time of interaction.

In some non-limiting embodiments or aspects, the mobile application datareceived may be from a predetermined period of time. For example, themobile application data may represent interactions initiated on aparticular day or from a range of dates and/or times. The mobileapplication data may represent interactions initiated within aparticular range of hours, for example.

With continued reference to FIG. 3 , at step 308, process 300 mayinclude determining a region identifier for each transaction based onthe transaction location. In some non-limiting embodiments or aspects,the transaction location may be based on the geographic location of thetransaction. In some non-limiting embodiments or aspects, the region maybe determined using a GIS tool (e.g., a spatial join operation, apoint-in-geometry algorithm, and/or the like). In some non-limitingembodiments or aspects, a neighborhood identifier for each transactionmay be determined based on the transaction location.

With continued reference to FIG. 3 , at step 310, process 300 mayinclude determining a region identifier for each interaction based onthe interaction location. In some non-limiting embodiments or aspects,the interaction location may be based on the geographic location of theinteraction. In some non-limiting embodiments or aspects, the region maybe determined using a geographic information system (GIS) tool (e.g., aspatial join operation, a point-in-geometry algorithm, and/or the like).In some non-limiting embodiments or aspects, a neighborhood identifierfor each interaction may be determined based on the interactionlocation.

With continued reference to FIG. 3 , at step 312, process 300 mayinclude generating a transaction signature for each account identifierbased on the region of each transaction initiated with the accountidentifier. This may result in a plurality of transaction signatures. Insome non-limiting embodiments or aspects, the transaction signature maybe based on the region identifiers of each region in which a transactionfor the account identifier took place. For example, the transactionsignature may contain each region identifier associated with thetransactions of the account identifier. In some non-limiting embodimentsor aspects, the transaction signature may be based on the neighborhoodidentifier associated with the transaction. In some non-limitingembodiments or aspects, the transaction signature may be based on thetransaction time. In some non-limiting embodiments or aspects, atransaction signature may be generated for only account identifiersassociated with transactions located within a predetermined minimumnumber of unique regions (e.g., a transaction signature is onlygenerated if transactions associated with the account identifier arelocated in at least three different regions).

In some non-limiting embodiments or aspects, more than one transactionsignature may be associated with an account identifier. In somenon-limiting embodiments or aspects, a transaction signature may begenerated based on a predetermined interval of time (e.g., every hour,every day, every week, and/or the like) such that each accountidentifier is associated with a plurality of transaction signaturesincluding a transaction signature for each interval of time for eachinterval in a period of time. A longer predetermined interval of time(e.g., several weeks, a month, and/or the like) may result in a largernumber of transactions associated with the transaction signature and alarger number of region identifiers and/or neighborhood identifiersassociated with the transaction signature. An increased number ofassociated region identifiers and/or neighborhood identifiers willresult in a more unique transaction signature. Therefore, a longerpredetermined interval of time may increase the uniqueness of thetransaction signature. The transaction signatures may be generated atthe end of each predetermined interval of time, for example. In somenon-limiting embodiments or aspects, the transaction signatures forseveral intervals of time may be generated at once, such as wheninitiated by a user after specifying a number of intervals of time orautomatically after a period of time has passed or another triggeringevent has occurred.

In some non-limiting embodiments or aspects, a home region may bedetermined based on the transaction signatures. For example, a homeregion may be determined based on the locations of transactionsassociated with everyday merchant categories (e.g., grocery stores, gasstations, and/or the like). A high concentration of transactionsassociated with everyday merchant categories in a particular region mayindicate that the user's home is in that particular region. For example,it may be determined that a user's home is in a particular region basedon the number of such transactions (including the actual number or arelative number based on other transactions) in that region meeting athreshold.

With continued reference to FIG. 3 , at step 314, process 300 mayinclude generating an interaction signature for each user identifierbased on the region of each interaction associated with thecorresponding user identifier. This may result in a plurality ofinteraction signatures. For example, the interaction signature for auser may be based on the region identifiers of each region in which aninteraction for the user identifier corresponding to that user tookplace. In some non-limiting embodiments or aspects, the interactionsignature may be based on the time of the interaction. In somenon-limiting embodiments or aspects, the interaction signature may begenerated using the same method as generating the transaction signature,but based on the interaction data instead of the transaction data. Insome non-limiting embodiments or aspects, an interaction signature maybe generated for only user identifiers associated with interactionslocated within a predetermined minimum number of unique regions (e.g.,an interaction signature is only generated if interactions associatedwith the user identifier are located in at least three differentregions).

In some non-limiting embodiments or aspects, more than one interactionsignature may be associated with a user identifier. For example, aninteraction signature may be generated based on a predetermined intervalof time (e.g., every hour, every day, every week, and/or the like) suchthat each user identifier has an interaction signature for each intervalof time over a period of time. A longer predetermined interval of time(e.g., several weeks, a month, and/or the like) may result in a largernumber of interactions associated with the interaction signature and alarger number of region identifiers and/or neighborhood identifiersassociated with the interaction signature. An increased number ofassociated region identifiers and/or neighborhood identifiers willresult in a more unique interaction signature. Therefore, a longerpredetermined interval of time may increase the uniqueness of theinteraction signature. The interaction signatures may be generated atthe end of each predetermined interval of time. The interactionsignatures for several intervals of time may be generated at once, suchas when initiated by a user after specifying a number of intervals oftime, or automatically.

In some non-limiting embodiments or aspects, a home region may bedetermined based on the interaction signatures. A home region may bedetermined based on the locations of frequent WiFi® connections. Forexample, a high concentration of interactions (e.g., a number ofinteractions or relative interactions satisfying a threshold and/or alength of connection over a specified period of time satisfying athreshold) associated with a particular WiFi® connection in a particularregion may indicate that the user's home is in that particular region.

With continued reference to FIG. 3 , at step 316, at least onetransaction signature may be matched to at least one interactionsignature. In some non-limiting embodiments or aspects, a transactionsignature may be matched to an interaction signature based on at leastone region identifier associated with the transaction signature and theinteraction signature. In some non-limiting embodiments or aspects, thetransaction signature may be matched to the interaction signature basedon at least one neighborhood identifier associated with the transactionsignature and the interaction signature. In some non-limitingembodiments or aspects, a match may be made for multiple intervals oftime such that a separate match is made for each interval (e.g., everyday, every week, etc.). A larger interval of time may result in anincrease in the number of region identifiers and/or neighborhoodidentifiers associated with the transaction signature and/or interactionsignature. A larger number of region identifiers and/or neighborhoodidentifiers may increase the uniqueness of the transaction signatureand/or interaction signature. Matching a transaction signature with aninteraction signature based on a higher number of region identifiersand/or neighborhood identifiers will result in an increased confidencethat the transaction signature is associated with the same user as theuser associated with the matched interaction signature. Therefore, alarger interval of time may increase the uniqueness of the transactionsignature and/or interaction signature and increase confidence that thecorrect interaction signature is matched to the correct transactionsignature. Matching a transaction signature to an interaction signaturemay include, for example, matching the transaction identifier associatedwith the transaction signature to the interaction identifier associatedwith the interaction signature.

In some non-limiting embodiments or aspects, matching at least onetransaction signature to at least one interaction signature may be basedon a difference between the transaction time of at least one transactionassociated with the transaction signature and the time of interaction ofat least one interaction associated with the transaction signature. Ifthe difference between the transaction time and the time of interactionsatisfies a predetermined threshold value (e.g., to be less than orequal to a predetermined value), the times may be determined to be amatch. For example, an interaction may be required to have a time ofinteraction of an interaction associated with the interaction signatureto occur within one day, one hour, or 30 minutes of a transaction timeof a transaction associated with the transaction signature in the sameregion in order for the transaction signature and the interactionsignature to be matched.

With continued reference to FIG. 3 , at step 318, at least one accountidentifier may be linked to at least one user identifier based on thematching. For example, in some non-limiting embodiments or aspects, anaccount identifier may be linked to a user identifier if transactionsignatures associated with the account identifier and interactionsignatures of the user identifier are matched more than one time, orafter a predetermined number of matches and/or percentage of matches(e.g., 90% of the transaction signatures associated with an accountidentifier are matched to interaction signatures associated with a useridentifier with at least 10 transaction signatures analyzed). Inresponse to more than one account identifier being linked to the sameuser identifier, or more than one user identifier being linked to thesame user identifier, the predetermined number of matches and/orpercentage of matches required to link the user identifier to theaccount identifier may be increased. A larger number of matches willincrease the confidence that the linked account identifier and linkeduser identifier are associated with the same user. In some non-limitingembodiments or aspects, a common matching key may be created for alinked user identifier and account identifier.

In some non-limiting embodiments or aspects, if more than one accountidentifier is linked to one user identifier, and/or if more than oneuser identifier is linked to one account identifier, the predeterminedthreshold value for the difference between the transaction time and thetime of interaction may be decreased. After the threshold is decreased,at least one transaction signature may be matched to at least oneinteraction signature. The matching may be based on the decreasedthreshold. At least one account identifier associated with the matchedtransaction signature may be linked to at least one user identifierassociated with the matched interaction signature.

In some non-limiting embodiments or aspects, in response to more thanone interaction signature being matched to the same transactionsignature, or in response to more than one transaction signature beingmatched to the same interaction signature, a new set of regions may begenerated. Generation of the new set of regions may be used to refinethe results such that a single interaction signature can be linked to asingle interaction signature. In some non-limiting embodiments oraspects, the new set of regions may be generated such that at least twoof the new regions overlap with at least one of the regions associatedwith a linked transaction signature or a linked interaction signature.In some non-limiting embodiments or aspects, the new set of regions maybe generated such that two or more interactions signatures and/or two ormore interaction signatures that were located in the same originalregion are located in at least two different new regions.

In some non-limiting embodiments or aspects, the new set of regions(e.g., a plurality of new regions) may be generated such that theaverage size of the new regions is smaller than the average size of theoriginal regions. For example, the new set of regions may contain ahigher number of regions than the original set of regions. The new setof regions may split one or more original region into two or more newregions. In some non-limiting embodiments or aspects, at least one ofthe new regions may be larger than the original regions (e.g., one ormore original regions with no transactions or interactions may becombined to make a larger region). In some non-limiting embodiments oraspects, the new set of regions may include the same boundary lines asthe original set of regions in addition to new boundary lines for thegeneration of the new regions.

Once the new set of regions is generated, the new region for eachtransaction based on the transaction location is determined. The newregion for each interaction based on the interaction location may alsobe determined. In some non-limiting embodiments or aspects, a newtransaction signature and a new interaction signature may be generatedbased on the new regions associated with each transaction andinteraction. In some non-limiting embodiments or aspects, the newinteraction signature and new transaction signature may be matched basedon the new regions associated with the new interaction signature and newtransaction signature. In some non-limiting embodiments or aspects, theaccount identifier associated with the matched new transaction signaturemay be linked to the user identifier associated with the new interactionsignature.

In some non-limiting embodiments or aspects, the new regions may only bedetermined for the transactions associated with a portion of the accountidentifiers and/or interactions associated with a portion of the useridentifiers. For example, for account identifiers that are linked in aone-to-one relationship with user identifiers, no new interactionsignatures or transaction signatures may be generated for theinteractions and transactions associated with the account identifiersand user identifiers.

In some non-limiting embodiments or aspects, the new regions may begenerated if no transaction signature is matched to an interactionsignature. For example, if no matches are made, the new set of regionsmay include a fewer number regions than the set of original regionsand/or the new regions may be larger in geographic size than theoriginal regions.

In some non-limiting embodiments or aspects, the generation of the newset of regions may occur before the linking step of 318 such that a newset of regions is generated in response to more than one interactionsignature being matched to the same transaction signature (e.g., amany-to-one match) or in response to more than one transaction signaturebeing matched to the same interaction signature (e.g., a one-to-manymatch). Generation of the new set of regions may be used to refine theresults such that a single transaction signature can be matched to asingle interaction signature (e.g., a one-to-one match). In somenon-limiting embodiments or aspects, the generation of new sets ofregions may be repeated until a one-to-one match is achieved.

In some non-limiting embodiments or aspects, in response to more thanone interaction signature being matched to the same transactionsignature, or in response to more than one transaction signature beingmatched to the same interaction signature, the predetermined interval oftime of the interaction signatures and/or the transaction signatures maybe lengthened and a new set of interaction signatures and transactionsignatures may be generated. A lengthened predetermined interval of timemay result in more interactions and/or transactions being included ineach interaction signature and transaction signature. The additionalinteractions and transactions may increase the number of regions and/orneighborhoods associated with the interaction signature and/ortransaction signature, resulting in more unique interaction signaturesand/or transaction signatures. This will also result in a decreasedlikelihood that an interaction signature will be matched to atransaction signature, which will decrease the number of multiplematches to the same transaction signature or interaction signature.Therefore, lengthening the predetermined interval of time of theinteraction signatures and/or the transaction signatures may result inincreased uniqueness of the interaction signatures and/or transactionsignatures and increase confidence in a single match of a transactionsignature to an interaction signature.

In some non-limiting embodiments or aspects, in response to at least oneinteraction signature not being matched to a transaction signature, orin response to at least one transaction signature not being matched toan interaction signature, the predetermined interval of time of theinteraction signatures and/or the transaction signatures may beshortened and a new set of interaction signatures and transactionsignatures may be generated. A shortened predetermined interval of timemay result in fewer interactions and/or transactions being included ineach interaction signature and transaction signature. The fewerinteractions and transactions may decrease the number of regions and/orneighborhoods associated with the interaction signature and/ortransaction signature, resulting in less unique interaction signaturesand/or transaction signatures. This will also result in an increasedlikelihood that an interaction signature will be matched to atransaction signature, which will increase the number of matches betweentransaction signatures and interaction signatures.

In some non-limiting embodiments or aspects, the lengthening orshortening of the predetermined interval of time of the interactionsignatures and/or the transaction signatures may occur before thelinking step of 318. The lengthening or shortening of the predeterminedinterval of time of the interaction signatures and/or the transactionsignatures may be repeated for all or a subset of the interactionsignatures and/or transaction signatures until a one-to-one match isachieved.

In some non-limiting embodiments or aspect, the lengthening orshortening of the predetermined interval of time of the interactionsignatures and/or the transaction signatures and/or the generation ofthe new set of regions may occur in response to more than one accountidentifier being linked to the same user identifier, or more than oneuser identifier being linked to the same account identifier.

In some non-limiting embodiments or aspects, a match score may begenerated to determine the likelihood of a match between a useridentifier and an account identifier. In some non-limiting embodimentsor aspects, a match score may be generated for a potential match betweeneach potential pair of user identifier and account identifier. The matchscore may be generated utilizing an algorithm, such as a pairwisealignment algorithm, dynamic time warping, Needleman-Wunsch algorithm,and/or the like. The match score may increase confidence that the matchis correct. In some non-limiting embodiments or aspects, the match scoremay be calculated by comparing the neighborhoods and/or regionsassociated with each transaction signature associated with the accountidentifier to the neighborhoods and/or regions associated with eachinteraction signature associated with the user identifier. In somenon-limiting embodiments, only a subset of the transaction signatures iscompared to a subset of the interaction signatures. The subset may bebased on the transaction signatures and interaction signatures beingassociated with a specified date range and/or time interval range.

In some non-limiting embodiments or aspects, when calculating a matchscore, each pair of regions and/or neighborhoods (e.g., for each regionand/or neighborhood of the interaction signature of the user identifiercompared to a region and/or neighborhood of the transaction signature ofthe account identifier or vice versa) may be assigned a value. Forexample, if the user identifier and the account identifier areassociated with multiple interaction signatures and transactionsignatures, then the interaction signatures may be compared to thetransaction signatures that encompass the same time interval as therespective interaction signature. If both the transaction signature andthe interaction signature are associated with the same region and/orneighborhood, then a match value (e.g., a value of 1) may be added tothe match score of the pair for each region that the transactionsignature and the interaction signature have in common. If thetransaction signature and the interaction signature are associated withan unequal number of regions and/or neighborhoods, such that either thetransaction signature or the interaction signature is associated with ahigher number of regions and/or neighborhoods than the other, then foreach extra region and/or neighborhood, a gap penalty value (e.g., avalue of −0.5) may be added to the match score which is lower than thematch value and may be a negative value.

In some non-limiting embodiments or aspects, if the interactionsignature is associated with a region and/or neighborhood that is notassociated with the transaction signature, and the transaction signatureis associated with a region and/or neighborhood that is not associatedwith the interaction signature, then a distance value is calculated forthe mismatched regions and/or neighborhoods which is added to the matchscore. For example, the distance value may be calculated based on adistance between the mismatched regions and/or neighborhoods (d) and themaximum (max) distance of the regions and/or neighborhoods (d_(max)).The max distance is the largest distance between any two regions and/orneighborhoods. The max distance may be calculated based on the distancebetween the centroids of the regions and/or neighborhoods. The distancebetween the mismatched regions and/or neighborhoods may also becalculated based on the distance between the centroids of the regionsand/or neighborhoods. The distance value can then be calculated as1−d/d_(max). If d is equal to d_(max), then the distance value would bezero, resulting in no match between the region of the user identifierand the region of the account identifier. If an interaction ortransaction is located in more than one neighborhood, each neighborhoodof the interaction or transaction may be compared in order to find thebest match (e.g. the highest value). In some non-limiting embodiments oraspects, the distance values added to the match score may be the highestdistance values calculated based on all of the possible combinationsbetween the regions and/or neighborhoods of the transaction signatureand the regions and/or neighborhoods of the interaction signature.

In some non-limiting embodiments or aspects, the total match score for apair of the user identifier and account identifier may be calculated byadding each of the gap penalties, match values, and distance values ofall transaction signatures and interaction signatures associated withthe user identifier and account identifier. A higher sum value indicatesa higher relevance and more robust match between the user identifier andthe account identifier. For example, if the sum value satisfies (e.g.,meets or exceeds) a predetermined threshold value, it may be determinedthat the match is a confident match. In some non-limiting embodiments,only a subset of the transaction signatures and interaction signaturesassociated with the user identifier and account identifier may be usedto compute the total match score (e.g., only the transaction signaturesand interaction signatures associated with a specified date range).

In some non-limiting embodiments or aspects, the use of the total matchscore and neighborhoods may provide benefits such as allowing forallowing for transactions and interactions that occur at differenttimes, and thus different locations, to still be able to be correlatedto each other. The use of the total match score and neighborhoods mayalso reduce the computational resources necessary to calculate thedistance value compared to calculating the distance value using thelatitudinal and longitudinal coordinates of each interaction andtransaction, thereby improving the speed and efficiency of the computingdevice.
